VL4151 Analog IC Design Syllabus:
VL4151 Analog IC Design Syllabus – Anna University PG Syllabus Regulation 2021
COURSE OBJECTIVES:
Analog Circuits play a very crucial role in all electronic systems and due to continued miniaturization, many of the analog blocks are not getting realized in CMOS technology. The most important building blocks of all CMOS analog IC will be the topic of study in this course.
The basic principle of operation, the circuit choices and the tradeoffs involved in the MOS transistor level design common to all analog CMOS ICs will be discussed in this course.
The specific design issues related to single and multistage voltage, current and differential amplifiers, their output and impedance issues, bandwidth, feedback and stability will be dealt with in detail.
